1.
The middle level on a two storey structure.
What separates the top floor from the bottom floor.
If one is on the lower level the roof is above them, alternatively if one is on the upper level the floor is below them.
Since neither, by technical definition, is the floor or the roof, the term "Floof" best describes this.
